摘要：利用改进的捕集装置和捕集方法,用2,4-二硝基苯肼溶液捕集卷烟主流烟气中的羰基化合物,再用HPLC、MS进行定性定量分析。建立并优化了高效液相色谱方法:采用ZorbaxEclipseXDBC8150mm×4.6mm(5μm)色谱柱为分离柱,流动相为乙腈-水体系,洗脱方式为梯度洗脱,柱温为25°C,检测波长为365nm。考察了该方法的定量线性范围、重现性、回收率和最低检出限,结果满足分析要求。同时对几种不同品牌的卷烟烟气中的羰基化合物进行分析,对甲醛、乙醛、丙醛、丁醛、丙烯醛、巴豆醛、丙酮和丁酮进行了定量测定,并对一未知组分进行了定性,确定为五碳羰基化合物。
2,4-Dinitrophenyhydrazine solution was used to trap the carbonyl compounds in tobacco smoke by improved trapping method. Dinitrophenylhydrazone derivatives in the trapped solutions were qualitatively and quantitatively analyzed by high performance liquid chromatography (HPLC) and mass spectrum (MS). HPLC method was established and optimized as follows: Zorbax Eclipse XDB C8 150 mm × 4.6 mm (5 μn) as separation column, acetonitrile/water as mobile phase, gradient elution, 25°C as separation temperature, UV detection at 365 nm. The linear range, recovery, repeatability and low detect limit about the HPLC method were investigated, and results meet the requirement. The carbonyl com-pounds, including formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, butanone crotonaldehyde and butylaldehyde were quantitatively determinated in several kinds of cigarette, and an unknown compound in the trapped solution was collected and identified as a carbonyl compound with 5 carbons.
